Thanks Ryan for cleaning up after my laziness. :) Here are just a few

last little changes.  ->datafile should be initialized... but doing so
brings up the fact that the check in run_rewritemap_programs() was
expecting ->datafile to have a string attached to it.  For clarity,
let's just use argv[0] there.  And since we've reinstated the use of
->checkfile, we no longer need that extra apr_stat() I hacked in,
so let's get rid of it.
